Satellite-retrieved aerosol and ocean surface properties from the PACE SPEXone instrument. The dataset includes aerosol optical depth, single-scattering albedo, refractive index, size distribution metrics, and coupled ocean surface parameters. It is produced by the OB_CLOUD organization using the RemoTAP algorithm.
Use Cases
- Aerosol-climate and air-quality studies based on spectral aerosol optical depth and microphysical properties.
- Providing aerosol context for ocean-color atmospheric correction based on coupled surface and ocean body properties.
- Model evaluation and data assimilation based on variables like aerosol layer height, lidar ratios, and fine/coarse mode metrics.
- Cross-sensor analyses with OCI/HARP2 products based on the suite's geophysical variables.
Strengths
- Includes a suite of over 20 core geophysical variables, such as aerosol optical thickness, single-scattering albedo, and chlorophyll-a concentration.
- Provides coupled atmosphere–ocean inversion data, reporting both aerosol properties and ocean surface parameters like wind speed.
- Data is from a specific satellite instrument (PACE SPEXone) and algorithm version (RemoTAP 3.0).
Limitations
- Row count, file formats, and column-level documentation are unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
- Data coverage is limited to ocean regions as described.
Provenance
